Thou art That
Framing the Eden myth as being about a sin of disobedience is only one way of reading the story. It's also a relatively recent and specifically Christian way of understanding it. I wouldn't use that reading to understand ancient Jewish attitudes (or modern Jewish attitudes either, for the most part).
The Jewish account of Genesis is the same as that of the Christian account. Both tell of the disobedience of Adam and Eve. Here is the Jewish text from the Torah:
Genesis - Chapter 3 (Parshah Berei****) - Tanakh Online - Torah - Bible
However, the doctrine of Original Sin and that it was inherited by all of mankind may have come later. The point of all this is to demonstrate the modern Christian view that the blood sacrifice of Jesus was necessary as the only means whereby the Gates of Paradise could be reopened after the sin of disobedience of Adam and Eve had closed them. But I am further suggesting (strongly) that the Jewish mystic called Yeshua never knew of this idea. Firstly, he was crucified by Rome for sedition on the one hand, and for blasphemy by the Jewish high priests on the other. Blood sacrifice as a means of sin redemption was never a consideration. That was added later from the Mithraic myth.
Now, having said all that, my own belief is that the account of Adam and Eve, both Jewish and Christian, are corrupted texts. The original story, probably from Persia, begins the same way, with God warning A&E about the 'Forbidden Fruit', but when God goes away, he then reappears to them as the serpent in order to insure that A&E partake of the Fruit, because the Fruit is a symbol of Higher Consciousness and Divine Union. IOW, God WANTS them to enjoy the free unconditional gift of Divine Union with him. Story end. No sin. No disobedience, and all's well that end's well. Remember that the serpent told A&E that God did not want them to eat of the Fruit because they would then 'see as God sees', which is none other than God Consciousness. God is simply using reverse psychology on his children with a kind of piece de resistance. Tell a child he can have anything he wants in his room, but of the box in the corner, he is not to open. Of course, the first thing the child will do is to open the box.
